SPECIFICATION forming part of Letters Patent N o. 731,618, dated June 23, 1903.

i Application filed November 19, 1902. Serial No. 131.980. (No model.)

To al?, whom it may concern.-

Be it known that I, ALoNzo E. RHoADEs, a citizen ot' the United States, and a resident of Hopedale, county of Worcester, State of Massachusetts, have inivented an Improvement in Bobbin-Holders, of .which the following description, in connection with the accompanying drawings, is a specification, like characters `on the drawings representing like parts.

This invention has for its object the production of a bobbin-holder embodying certain novel features of constructionand operation to be hereinafter fully described in `may he drawn od from tho bobbin more easily and with less strain. e i Figure l is a side elevation of a bobbinholder embodying one form of my invention. Fig. 2 is an enlarged cross-sectional 'detail `thereof on the line 212, Fig. 3, looking toward the left." Fig.` 3 is a longitudinal section of the head of the ove'rhanging arm on the line 3 3, Fig. 4, viewed in the directionof arrow 3X. Fig.` 4 is an under side view'of4 the head of the arm on the line 4 4, Fig. 2. Fig.

` or the like, the bracket a,

5 is a longitudinalcentral section ofa modified form of head with a dif-ferent devicet'or augmenting the resistance of Vthe guards. Fig. 6 is a transverse section, also enlarged,

`ou the line 6 6, Fig. 5, looking toward the left, the rest for the bobbin, the guards, and theupturned part of thearm being also shown; and Fig. `7 is a top orplan View ofthe guard- `supportshown in Figs. 5 and 6.

Referring toFig. l, the clampAX, having a set-screw ctx to retain the bobbinholder in place on the supporting-bar BX of a spooler to which the pan or rest d is attached yby a bolt o', and the upturned overhanging arm A, having alateral enlargement or back-stop A for the bobbin, may be and are all substantially of wellknown or usual construction. I The overhanging head A2 of the arm is enlarged and cored out or chamber-ed, as at o2, Figs. 2, 3, and 4, to receive two upright transverse partitions d3, herein shown as secured by screws l to a bottom plate a4, attached to the under face of the head by screws l2. notched in their tops, as at a5, Fig. 2, to form seats in which the side guards are pivotally supported, and each partition is cut away or recessed in its bottom, as at a, (see Fig. 4,) the recesses of the partitions being diagonally opposite each other. A connecting device, shown as a lever c, having forked-or bifurcated ends c', is fulcrumed at its center on a headed stud a7 on the bottom plate a4, the lever resting on the upper face of the plate and extending diagonally across it, the bifurcated ends of the lever passing through and beyond the recesses a6 of the partitions d3.

The guards in my present invention are made of stout wire, as usual, but bent topresent a straight top portion gX and depending slightly-divergent ends g, which are bent at their lower extremities to present elongated opposite loops g2, open at their inner ends at g3, Fig. l, the open ends of the loops being separated from each other, as shown. The straight top gx of each guard is seated in the opposite notches or recesses a of the partitions a3, the ends g passing downward at the outer faces of the partitions through transverse slots 0.8 in the bottom plate a4, permitting the requisite lateral movement of the guards. As shown in Fig. 4, the rear end of one guard is loosely embraced by the adja- The partitions are cent forked end of the lever c and the other end of the latter embraces in like manner the front end g of the other guard. If either guard is swung outward unduly, as by an improper movement of the bobbin toward the side of the rest d, the end of the lever c engaged rby such guard will be moved outward and the opposite end of thelever will be oppositely swung to thereby swing outward the other guard in engagementtherewith. The resistance ofthe guard againstwhich the bobbin presses will thus be augmented or increased by the force required to swing outward the other guard and the lateral movement ofthe bobbin will be stopped.

' of the yarn as it was laid upon the bobbin.

, lateral movement ofthe bobbin.

The guide is made alike at each end, so that it is immaterial from which end the yarn draws at the beginning.

In Figs. 5. and 6 I have shown a modication of the means for increasing orau'gment ing the resistance of either guard to undue The head A20 of the overhanging arm is recessed or chambered, as before, as at d20, and at its rear end it is provided with an upright slot a21 and an adjacent external ear @22. An arm 020 is fulcrumed at 021 on the ear and extends into the chamber ofthe head, the inner end of the arm being turned up and widened laterally, as at C22, and provided with a transverse slot 023. A guard-support a3() is inserted in the head from beneath and held in place by a screw 131, Fig. 5, said support having at its rear end upright lugs (L32, separated at their bases by aslot or opening w33, in which the arm 02 is free to move. At its front end the support has a transverse upright projection e134, provided in its top with notches 0.35

in alinement with similar notches as in the lugs u32, (see Fig. 7,) the front end of the support extending beyond the projection to form a tongue Q37. The, guards maybe made substantially as hereinbefore described; but the upper portion gX of each is provided with a crank portion gio, which cooperates with the lateral end 622 of the arm C20. The guards are inserted in the slot 023 before the parts are assembled, 4and then the arm is mounted on the ear @22. After this the guard-support C630 is put in position, the parts g of the guards resting in the notches us5 @Si and being pivotally supported thereby. Referring to Fig.

6, the cranks g20 are shown as inturned, and if a guard is swung outward undulyits crank will act to depress the arm C20, and by the connection of t-he latter with the crank of the other guard said crank will be pulled downward to thereby swing its guard outward, augmenting the resistance of the first-named guard to outward movement. The tongue n.37 permits the requisitev swing of the front ends ot' the two guards.

Having fully described my invention, what I claim as new, and desire to secure-by Letters Patent, is-

1. In a bobbin-holder, a rest for the bobbin, laterally-swinging side guards to retain the bobbin on the rest, and means to automatically augment the resistance of either guard to improper lateral movement of the bobbin.

2. In a bobbin-holder, a rest for the bobbin, laterally-movable side guards pivotally supported at their upper ends, and means controlled by undue outward movement of either guard to augment its resistance to such undue movement.

3. In a bobbin-holder, a rest for the bobbin, laterally-swinging side guards to retain the bobbin on the rest, and means to cause the guards to movel laterally and oppositely in unison.

4. In a bobbin-holder, a rest for the bohbin, laterally-swinging side guards to retain the bobbin on the rest, and connections between the guards, whereby undue lateral outward movement of either causes and is resisted by corresponding outward movement of the other guard.

5. In a bobbin-holder, a rest for the bobbin, laterally-swinging side guards to retain the bobbin on the rest, and connecting means between the guards near their upper, pivotally-supported ends, whereby undue outward movement ot either guard due to lateral movement of the bobbin on the rest is transmitted to the other guard, to swing the same oppositely and thereby augment the resistance of the guard engaged by the bobbin.

6. In a bobbin-holder, a rest for the bobbin, an upturned, overhanging arm, laterallymovable side guards for the bobbin, pivotally mounted on the overhanging arm and depending therefrom, and means mounted on the arm and connecting the guards, whereby outward movement of either guard causes a corresponding outward, opposite movement of the other guard.

7. .In a bobbin-holder, a rest for the bobbin, and laterally-swinging guards at the sides of the bobbin, one of said guards having its lower ends bent to present opposite, elongated loops open at their inner, separated ends, to permit the yarn in unwinding to pass into one or the other loop, through the open space between the inner ends of the loops.

8. In a bobbin-holder, a rest for the boh-v bin, and laterally-swinging guards at the sides of the bobbin, said guards having their lower ends bent to present opposite, elongated loops open at their inner, ends, the lower edges of the loops being separated from each other to admit the yarn to a loop.

9. In a bobbin-holder, a rest for the bobbin, laterally-swinging guards at the sides of the bobbin, each guard having its lower end bent to present opposed, elongated loops open at their inner, separated ends, and means to augment automatically the resistance ot either guard to undue outward movement.

In testimony whereof I have signed my name to. this specification in the presence ot two subscribing witnesses.
